Eta

For the past 6 years our teams have been working to build the world’s fastest human-powered vehicle and surpass the current level-ground speed record of 133.8 km/h (83.1 mph). Since  2009 we have built and raced numerous bikes, with each iteration surpassing the last.  Our current bike, "Eta" is the fastest bike we've made yet and if it breaks the record this year, will become the fastest human powered vehicle on earth.    Go here for the latest news on Eta's attempt the world record.

Eta is all about the pursuit of ultimate efficiency. We have begun with a clean-sheet design, and working from the ground up we’ve evaluated the best design options for every component and subsystem. We will rely on the team’s broad experience to reduce risk, weighing the challenge of implementing each novel solution against our confidence in obtaining the potential speed gains. We know that with consistent incremental improvements in each subsystem, we can greatly improve on our past performance, breaking down preconceived limits of what is possible.

Aerodynamics: We use Computational Fluid Dynamics and optimal aerodynamic shaping techniques, proven-out with on-road testing, to design an exterior shape with drag more than 100 times less than that of the most streamlined cars.

Drivetrain: We have focused on minimal-loss chain drive options, lower-drag bearings, and a range of other strategies to ensure every bit of power produced by the pilot makes it to the road.

Rolling Resistance & Wheels: We have found the world’s best handmade tires, incorporated the largest possible wheels for lower rolling resistance and better handling, and optimized the aerodynamic design of the spokes to squeeze out every bit of performance.

Human Power & Ergonomics: A custom lab-quality test rig will determine the best pilot position for efficient power production and positioning of mechanical components, and will aid in pilot training to obtain maximum output in the enclosed shell.

Since 2008, Aerovelo team members have worked with the University of Toronto Human-Powered Vehicle Design Team on very similar types of speedbikes, expanding our knowledge and consistently increasing our performance. The U of T HPVDT’s bikes have been designed primarily for the American Society for Mechanical Engineers’ Human-Powered Vehicle Challenge, a university competition in the US that aims to develop practical road-worthy vehicles. Even with these utility-focused designs, our riders have achieved successive speeds of 102 km/h (63.4 mph) in ACE, 116.9 km/h (72.6 mph) in Vortex, and 125.0 km/h (77.7 mph) in Bluenose.
